An acrobatic buccaneer swings from one rope to another in the rigging of a pirate ship. as she grasps the rope, her mass is m -68.2 kg; knots on the rope make the rope's effective mass mp -1.80 kg. from the height she grabs the rope, she swings up a further distance of 1.5 m. assuming that her collision with the rope is perfectly inelastic, answer the following questions: a) does her collision with the rope conserve energy? [y/n? ) (5 points) b) does the buccaneer's collision with the rope conserve momentum? (y/n? ) (5 points) c) neglecting any energy losses due to friction, air drag, etc., determine the velocity of the buccaneer-and-rope combined system right after she grabs the rope in m/s. (15 points) d) can you calculate the buccaneer's initial speed before she grabbed the rope from the information given?
